Dianthus plant named &#39;WP09 WEN04&#39;

ABSTRACT

A new cultivar of  Dianthus  plant named ‘WP09 WEN04’ which is characterized by compact plant habit and fragrant semi-double flowers which are predominantly salmon-pink in color, with a carmine colored eye. In combination, these characteristics set ‘WP09 WEN04’ apart from all other existing varieties of  Dianthus  known to the inventor.

SPECIES

DENOMINATION

‘WP09 WEN04’

BACKGROUND OF THE INVENTION

This application claims the benefit of priority under 35 U.S.C. 119(f) of the application for a grant of European Community Plant Breeders Rights which was filed for the instant plant variety on Mar. 9, 2009, Application Number 2009/0419.

The present invention relates to a new and distinct cultivar of hardy garden pink or carnation that is grown for use as a flowering plant for pots and containers and for planting in the garden and landscape. The new cultivar is known botanically as Dianthus×hybrida and will be referred to hereinafter by the cultivar name ‘WP09 WEN04’.

‘WP09 WEN04’ is a complex hybrid plant that is the product of a breeding program started by the inventor in 1985. The breeding program is conducted in a cultivated area of Houndspool, Dawlish, Devon, United Kingdom. The inventor selected ‘WP09 WEN04’ in 2004 for its fragrant flowers which are semi-double and predominantly salmon-pink in color, with a carmine colored eye.

‘WP09 WEN04’ resulted from the controlled pollination between two unreleased and unpatented selections of Dianthus from the inventor's breeding program, namely Selection “XIN 02.07” as male parent and Selection “BEL 03.07” as female parent.

‘WP09 WEN04’ is distinguishable from the male parent as follows: The flowers of the male parent are semi-double and magenta in color, with a dark magenta eye, whereas the flowers of ‘WP09 WEN04’ are semi-double and predominantly salmon-pink in color, with a carmine colored eye.

‘WP09 WEN04’ is distinguishable from the female parent as follows: The female plant is vigorous and produces tall plants with long flower stems, typically 30 cm-40 cm in length, whereas the flower stems of ‘WP09 WEN04’ are 15 cm-20 cm in length.

The variety of Dianthus which is considered by the inventor to most closely resemble ‘WP09 WEN04’ is Dianthus ‘Doris’ (unpatented). ‘Doris’ is similarly semi-double and salmon-pink in color. However, ‘Doris’ is a vigorous variety and exhibits greater overall plant size, longer flower stems and larger flowers than ‘WP09 WEN04’.

Asexual reproduction of ‘WP09 WEN04’ was first accomplished by the inventor in 2004 in a cultivated area of Houndspool, United Kingdom. The method of asexual propagation used was vegetative cuttings. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Dianthus cultivar ‘WP09 WEN04’. These traits in combination distinguish this cultivar from all other commercial varieties known to the inventor. ‘WP09 WEN04’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, however, without any variance in genotype.

1. Dianthus ‘WP09 WEN04’ exhibits a compact habit.

2. The flowers of Dianthus ‘WP09 WEN04’ are semi double.

3. The flowers of Dianthus ‘WP09 WEN04’ are predominantly salmon-pink in color, with a carmine colored eye.

4. Dianthus ‘WP09 WEN04’ blooms from April through October.

5. Dianthus ‘WP09 WEN04’ exhibits grey-green foliage.

6. At nine months of age, the height of the foliage mound of Dianthus ‘WP09 WEN04’ is 20 cm to 25 cm, and the width is 18 cm to 20 cm.

7. Dianthus ‘WP09 WEN04’ is perennial and is hardy to −15° C.

8. Dianthus ‘WP09 WEN04’ is suitable for use as a flowering plant in pots and containers.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Dianthus variety ‘WP09 WEN04’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘WP09 WEN04’.

The drawing labeled as FIG. 1 depicts an entire flowering plant.

The drawing labeled as FIG. 2 depicts a close-up view of the flower.

All drawings were made of 9 months old plants which have been grown in 1.5-litre containers in a cold glasshouse in Devon, United Kingdom. No chemicals were used to treat the plants. All drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar ‘WP09 WEN04’. Data was collected in spring from 1.5-litre container plants in spring, and grown indoors in Devon, United Kingdom. The color determinations are in accordance with the 2002 edition of The Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. The colors of stems, leaves, calyx, and epicalyx have been noted on plants which retain the characteristic waxy bloom of Dianthus. No chemicals were used to treat the plants. Growing conditions are typical to other Dianthus.
